SPECIFICATION forming part of Letters Patent No. 548,861, dated October29, 189 5.

Application filed December 24, 1894:. Serial No. 532,870. (No modelfl Toall whom it may concern.-

Beit known that I, JOHN D. BARTER, a citizen of the United States,residing at the city of St. Louis, State of Missouri, have invented acer= tain new and useful Improvement in Churn- Dasher-OperatingMechanism, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, wherein-- Figure 1 is a front elevationalview. Fig. 2 is a side elevational View. Fig. 3 is a detail' view of theright and left hand slotted drums. Fig. 4 is a detail of the clip forsecuring the smaller dasher to the rod. Fig. 5 is a detail of one of thepitmen cross-heads with roller for operating the slotted drums. Fig. 6is a detail ofthe clip for securing the larger dasher to thedrum-sleeve. Fig. 7 is a detail of the upper end of the sleeve of thelarger dasher. Fig. S is a detail sectional view of the dasher-bearings,and Fig. 9 is a detail of one of the buckets.

This invention relates to a new and useful improvement in mechanism foroperating churn dashers; and it consists, generallyr stated, incombining with a suitable motive power reciprocating pitmen, whichcooperate with oppositely-inclined slotted drums, Yto which are attachedthe churn-dashers; also, in the bearings for the several dashers. Otherminor features reside; in the peculiar construction, arrangement, and,combination of the several parts comprisingV my invention, all as willhereinafter be described, and afterward pointed out in the claims.

In the drawings, A indicates a suitable' Mounted in frame A is a circu-E is a tank for the motive fluid, supported on the frame A, and E is aconnection therebetween and the casing B, the passage of the luid to thewater-wheel being controlled by a needle-valve F. Y

B is a pipe leading from the bottom of casing B to conduct oft the usedwater.

- Ou the shaft of the water-wheel is a crankdisk G, upon the wrist-pinof which are mounted two pitmen H and Il', each connected to across-head I and I', respectively, moving in vertical guides J,supported by brackets extending from the casing B. Roll- 4ers K and Kare mounted upon the crossheads and are received in oppositely-inclinedslots in drums L and L. y

M is a rod upon which the'drum L is fixedly mounted, said rod also beingthe axis for the drum L', thclower end of the rod being formed angularin cross-section and provided with teeth m. On this angular portion isreceived a coupling-clip N, which is open at both ends and provided witha spring n, which engages the teeth 'm and retains the clip in a loweredposition whenI it is in engagement with the Vend of the rod V of thesmaller dasher. The

vthe drums L and L', so thatl when the parts fare assembled-that is, thedashers attachedthe drums will be elevated, L the greater distance, soas to leave a space between them and the bracket-pieces to reduce asmuch as possible .friction between the parts. VOne of the obj ectisfinproviding twopitmen H and'H .for the cross-heads is to allow for thiselevation ofthe drums.

S indicates one of the dashers, which I have termed the larger dasher,because it has a greaterscope than its'companion and surrounds the samein its travel. Extending from dasher S is a sleeve Q, already referredIOO to. The bearing for this dasher consists of a block T, provided witha center cup t, which receives a stud s, extending from a knob S on thedasher. To retain this relation between the parts, I provide the block Twith Wires or loops U, which arch over the knob and prevent displacementthereof.

V indicates what I have termed the smaller dasher,7 which has a bearingthrough a stud 'v in the lower cross-arm of the larger dasher. Rod Vextends from this dasher up through sleeve Q, and is connected to rod Mby coupling N.

W indicates a vessel in which the dashers operate.

The operation is as follows: Tank E being iilled with water and valve Fopened, the water, passing through pipe E', will strike the buckets Dand revolve the wheel. This will transmit motion to the crank-disk,which, through the medium of the pitman, will reciprocate the crossheadsI and I', causing rollers K and K to travel in the oppositelyinclinedslots inthe drums L and L, revolving them in opposite directions,likewise the dashers V and S, to which they are respectively connected.It will thus be seen that when the cross-heads descend dasher V revolvesto the left, while dasher S revolves to the right, and when thecross-heads ascend dasher V revolves in an opposite direction to theright,

while dasher S also reverses its direction and revolves to the left.

Although I have illustrated a particular form of motor, I do not wish tobe understood as excluding others, as it will be readily understood thatthe water-wheel could be replaced by a crank or pulley and the powerimparted to the crank-disk by manual or other power; also, in the changeof motive power other forms of supporting-framework could be substitutedfor that shown and described.

I am aware that many minor changes in the construction, arrangement, andcombination of the several parts of my device can be made andsubstituted for those herein shown and described without in the leastdeparting from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

l. The combination with a frame, of a casing mounted thereon, awater-wheel mounted in the casing, a crank-disk mounted on the shaft ofthe water-wheel, cross-heads which are reciprocated from saidcrank-disk, rollers on the cross-heads, drums which are provided withoppositely inclined slots for-receiving the rollers, a sleeve on one ofthe drums, a

drums to which is attached a dasher, and a rod on the other drum andwithin said sleeve to which is attached a dasher, substantially asdescribed.

3. Thecombination with a crank-disk having a single crank-pin, of twopitmen, one of which is of a given length and the other of a greaterlength and both connected at their upper ends to the said crank-pin, twocrossheads arranged one above the other in vertical alignment, the lowerend of the shorter pitman being connected to the uppermost cross-headand the lower end of the longer pitman being connected to the lowermostcrosshead, rollers on said cross-heads, two drums provided withoppositely-inclined slots and located in vertical alignment one abovethe other and mounted to rotate independently in opposite directions,means for imparting movement to said crank-disk, and two independentdashers which are connected to the said drums, substantially as hereinspecified.

4. The combination with drums L and L provided with oppositely inclinedslots, of rollers operating in said slots to revolve the drums, saidrollers having a :reciprocating movement, means for operating saidrollers, a rod M tixedly attached to drum L, forming an axis for drumL', and a sleeve on drum L which surrounds said rod, substantially asdescribed.

5. The combination with the rod M formed with teeth on its end, of thechurn rod V adapted to have its lower end seated in a socket, and acoupling between the two, comprising an open ended angular sleeve whichis provided with a spring for engagement with the teeth on the rod M,for holding the coupling in position, substantially as described.

In testimony whereof I hereunto affix my signature, in presence of twowitnesses, this 17th day of December, 1894.
